---Phil BV> Gopal, BV> I don't know what the difference is because I don't use BV> canned libraries. However I know that Protel used to have a paper BV> that described their naming conventions for footprints. I did a BV> quick search and couldn't find it for you but maybe you could look BV> for it yourself on their website. BV> Other than that place the parts and compare them. I suspect BV> you will find differing pad sizes and or differing pin 1 locations.
